There are also documented showings of 3-strip presentations of WINDJAMMER in Cincinnati (Twin Drive-In with some of the sailors in attendance on opening night) and in upper New York state. I believe that the sound came from a mono mag track on one of the machines. I think Marty Hart has a small section from one of those prints.

Yes it did:

1965
(38th) Class II Lighting ARTHUR J. HATCH of the Strong Electric Corporation, subsidiary of General Precision Equipment Corporation, for the design and development of an Air Blown Carbon Arc Projection Lamp

Where do I start, there were heaps of them. Metro Clayton Twin, Village Northland Twin, Hoyts Coburg - now Village Coburg Triple, Hoyts Maribyrnong, Hoyts Altona etc etc.

All of these drive-ins frequently ran 70mm in the 1960's, through the 1970's and into the 1980's. The Village Coburg Triple is equipped with 70mm Cinemeccanica Victoria 8's with Strong X60 C lamphouses, they can run changeovers or by Speco LP 270 platters. They have not run 70mm since at least 1984.

If you go to www.drive-insdownunder.com.au you will see photos of the 70mm Philips DP70's in action at Altona on the Victoria page under Australian drive-ins, also the Cinemeccanicas at Bulleen and Coburg.

Light was always a little better with 70mm, but the frame could have taken much more than we were equipped to put out. Clayton had Ashcraft Core-Lites and others ran Ashcraft Super-Cinex. These ran at around 160 amps with rotating positives and the light was OK for a drive-in even on the large Metro Twin curved drive-in screens - yep curved, look at the photo.

There were other 70mm drive-ins here in Melbourne and many others throughout the country. It is interesting to note that most of the drive-ins here did not even advertise that a print was screening in 70mm, the distributor would often just send it out.

There has been no 70mm ran in a Melbourne drive-in for at least 15 years.
